15. Encapsulation of BSA in polylactic acid–hyperbranched polyglycerol conjugate nanoparticles: preparation, characterization, and release kinetics.
Nanoparticles based on an amphiphilic copolymer with polylactic acid (PLA) grafted onto hyperbranched polyglycerol (HPG) were prepared by the use of BSA as a model protein. The characteristics of the nanoparticles were evaluated using particle size analyzer, transmission electron microscopy, and X-ray photoelectron spectroscopy. The secondary structure of BSA released from nanoparticles were analy...

11. Synthesis and physicochemical characterization of a novel amphiphilic polylactic acid-hyperbranched polyglycerol conjugate for protein drug delivery.
Amphiphilic copolymers with polylactic acid (PLA) chains grafted onto hyperbranched polyglycerol (HPG) have been synthesized and characterized. The copolymer nanoparticles with corona and core structure were formed by self-assembly in aqueous solution. The loading capacity and association efficiency were up to 23% and 86%, respectively. Protein release profiles with different copolymer composition...

9. Amphiphilic random glycopolymer based on phenylboronic acid: Synthesis, characterization, and potential as glucose-sensitive matrix.
This study is devoted to developing amphiphilic, random glycopolymers based on phenylboronic acid, which self-assemble to form nanoparticles (NPs), as a glucose-sensitive agent. Maleimide-glucosamine was copolymerized with 3-acryl aminophenylboronic acid in methanol at 70 degrees C. Using the nanoprecipitation method, NPs with a narrow size distribution were successfully generated. Transmission el...

8. Polyelectrolyte nanoparticles based on water-soluble chitosan-poly(L-aspartic acid)-polyethylene glycol for controlled protein release.
Water-soluble chitosan (WSC)-poly(L-aspartic acid) (PASP)-polyethylene glycol (PEG) nanoparticles (CPP nanoparticles) were prepared spontaneously under quite mild conditions by polyelectrolyte complexation. These nanoparticles were well dispersed and stable in aqueous solution, and their physicochemical properties were characterized by turbidity, FTIR spectroscopy, dynamic light scattering (DLS), ...

Acid and reduction dually cleavable amphiphilic comb-like copolymer micelles for controlled drug delivery
http://pubs.rsc.org/en/content/articlelanding/2013/py/c3py00252g
Disulfide- and acetal-functionalized comb-like copolymers (SACP) with poly(ε-caprolactone) (PCL) and poly(ethylene glycol) (PEG) side chains and a polymethacrylate backbone were synthesized and self-assembled for in vitro encapsulation and release of an anticancer drug, doxorubicin (DOX). Three step reactions inclu...

The anti-tumor efficiency of poly(L-glutamic acid) dendrimers with polyhedral oligomeric silsesquioxane cores
Peptide dendrimers represent superior drug carriers for their unique nanoarchitectures, excellent degradability and biocompatibility. In this research, poly(L-glutamic acid) dendrimers with polyhedral oligomeric silsesquioxane (POSS) as cores were synthesized. Tumor targeting moiety (biotin) and therapeutic drug doxorubicin (DOX) were immobilized on the dendrimers via pH-sensitive hydrazone bonds....

Effect of different concentrations of nitric acid on the conductivity of single-walled carbon nanotube transparent films
Single-walled carbon nanotubes dispersed in deionized water with sodium dodecyl benzene sulfonate were sprayed on UV and plasma treated polyethylene terephthalate to achieve transparent conductive films with excellent adhesion. The carbon nanotube films were further treated with different concentrations of nitric acid and characterized by adsorption spectra, Raman spectroscopy, four-point pr...

114. Exponentially increased nucleation ability for poly(L-lactide) by adding acid-oxidized multiwalled carbon nanotubes with reduced aspect ratios
Acid-oxidized multiwalled carbon nanotubes (A-MWCNTs) with a range of reduced aspect ratios (from about 11 to 5.8) were obtained by acid oxidization of MWCNTs in the mixture of HNO3 and H2SO4 for varying periods of 1, 3, 8 and 12 h, respectively. The aspect ratios and surface functionalization of A-MWCNTs were well characterized by scanning electron microscopy (SEM), Fourier transform infrare...
